沙沱水电站泄洪消能建筑物设计

乌江沙沱水电站的泄洪流量已超过3万m^3／s，总泄洪能量最高达13100Mw、单宽能量最高达125MW，其泄洪消能建筑物具有流量大、尾水深、低佛氏数和堰上水头高、单宽流量大等特点，是保障枢纽工程安全运行的关键性建筑物。为此，对沙沱水电站泄水建筑物的泄洪、消能布置进行了精心的研究，并通过水工模型试验作了验证，从而较好地解决了该电站泄洪消能建筑物的设计问题。

Design Of Construction Structure For Discharging Flood & Dissipation Of Shatuo Hydropower Station

The discharging flood volume of the station is more than 30, 000 m. 3/s, the total discharging energy is up to 13, 100MW, and the energy in a meter 125 MW. The structure for discharging flood and dissipation has these features such as large flow, deep tail water, low Fr parameter, high head on weir, large flow volume in a meter and etc. , is key one for insuring safe operation of the station. The designer, therefore, has elaborately researched the structure and examined it by model test resulting in making a good design.
